2 Claims. (01. 2481-126) This invention relates to an electric fan, and particularly to an electric fan adapted to be mounted on a substantially vertical support, such as a wall, or supported upon a substantially horizontal surface, such as a desk.

An object is to provide improved apparatus of the character set forth.

Heretofore, fans have been provided which may be mounted on a substantially vertical wall by means of a screw passing through the front or upper surface of the fan base and engaging the wall, or supported on a substantially horizontal surface, such as a desk. This arrangement provides a substantial mounting, but it is objectionable to a certain extent because of the unsightly appearance of the screw head when the fan is mounted on a wall, and the unsightly appearance of the screw hole when the fan is used on a desk or other horizontal surface. Accordingly, it is an object of; this invention to provide a fan that may be mounted on a substantially vertical support by means of a screw, or the like, passing through the base of the fan, or used on a substantially horizontal support, such as a desk, whereinthese objections are eliminated.

A further object is to provide a fan of the character set forth including means for mounting the same ona wall and a decorative cover for the mounting means.

A still further object is to provide a fan of the character set forth having a recess therein for mounting the same on a wall and a cover for the recess which is readily accessible from. the exterior of the fan for attaching or removing the same.

A still further object is to provide a fanineluding means for mounting the same on a wall and a cover for the mounting means which may be readily attached or removed from the fan from the exterior thereof, whereby the means for attaching the cover to the fan are not visible from th exterior of the fan.

These and other objects are effected by my invention as will be apparent from the following description and claims taken in accordance with the accompanying drawing, forming a part of this application, in which:

Fig. 1 is a side elevation, with parts broken away, of a fan embodying this invention shown resting on a horizontal surface;

Fig. 2 is a side elevation thereof showing the fan mounted on a substantially vertical wall;

Fig. 3 is an enlarged fragmentary top plan view showing theoover for the mounting means in position on the fansupport;

Fig. 4 is anenlarged f-ragmentary top plan view of the fan support, with the cover for the mounting means removed;

Fig. 5 is a view of the fan support and cover for the. mountingmeans as seen substantially along line V-V of Fig. 1; and,

Figs. 6 and '7 are sections taken along lines VI..-VI and VII-VII; respectively of Fig. 1.

Referring now to the drawing more in detail, in Figs. 1 and 2, an electric fan embodying this invention is shown. The fan includes ahollow base or support member H having an arm or standard I2 extendingtherefrom, a motor-housing I3 in which the motor parts are mounted, aset. offan blades-I6- which are rotated by the motor, and a fan guard Il which is attached tothe. motor housing. The upper end of the standard I2 is bifurcated to receive'one end of a bracket I8, theother end of which'is-attached to the motor. housing I3. The motor housing, the fan blades, and the guard are attached to the standard I2 by abolt I9'that passes through the bifurcated ends oflthe standardIZ and the bracket, I'8r, anda wingnut 2i! which screw threads on I thebolt I.9 to clamp. the bifurcated ends of the standard I2 and the bracket I8 together withsufiicient; pressure to prevent the assembly includingthelmotonthe fan blades, and the guard from tipping downward by gravity.

Thebase or support II is a thin walled hollow member, formed by die casting or any other suitable means. The arm or standard I2 may be formed integral with, the base member or attached thereto byany. suitable means. tomof the basemember II is closed by a flat plate .2 2 which rovides a large contact area onv which the fan rests whenplaced-ona horizontal y The. plate 22. may

be held in position by any suitable means, such BlT ELQ h as ho n; in F 1.

as screws or peening over the edge of the base member II.

When the fan is mounted on a substantially vertical wall 24, such as a wall of a room, as shown in Fig. 2, the flat bottom is positioned against the wall 24. As seen from the drawing, when the fan is mounted on the wall 24, the base member II is reversed or turned 180 in relation to the motor housing from its position when the fan is resting on a horizontal surface. This is done by removing the wing nut 20 and the bolt I9, then turning the base 180 with respect to the motor housing, and then replacing the bolt l9 and the wing nut 20.

The bot-.

The top wall of the base member ll, indicated generally by the reference character 25, extends upwardly and rearwardly from the front edge of the base I l, as seen in Fig. 1. As indicated at 21, Figs. 1, 2, and 4, a portion of the top wall is depressed or countersunk. This portion of the wall 25 is ichthyoidal-shaped and has a first aperture 29 and a second aperture 30 therein. A cylindrical casing 3|, defined by a cylindrical wall 32 and a bottom wall 34, surrounds the aperture 30 on the under side of the top wall 25 and depends from the top wall. The bottom wall 34 is substantially parallel to the plate 22 that closes the bottom of the base and it hasan aperture 36 therein which is substantially co-axial" with an aperture 31in the plate 22. To mount the fan on the substantially vertical wall 24, the fan is positioned, as shown in Fig.2,

with the plate 22 against the wall, and a screw 38 is inserted through the apertures 36 and 31' and screwed into the wall 24 far enough to hold the plate 22 tight thereagainst. As seen from Fig. 2, the head of the screw does not project beyond the top wall 250i the base member I I.

An ichthyoidal-shaped decorative cover mem-'. ber 49, slightly smaller than the depressed portion 21 of the top wall 25 of the base member H, is provided for covering the apertures 29 and 39 and the head of the screw 38,. This cover conforms to the general curved shape of the wall 25, and it has 'a substantially normal flange. .4l formed along its peripheral edge, except as indicated at 42, Figs. 1, 2, and 3, the flange being left off this portion so that a tool may be inserted between the cover 40 and the base member H at this point to remove the cover. This flange is slightly deeper than the depressed or countersunk portion 21 of the top wall 25 of the base member so that when the cover is placed in position over the apertures 29 and 39 it extends slightly above the top wall 25 of the base member I l and thus adds to the aesthetic qualities of the fan. A pair of resilient fingers 43 are formed integral with the cover 40, on opposite sides thereof. These fingers are bent outwardly intermediate the ends thereof to form ridges 44 therein which project beyond the peripheral edges of the cover 40. l

To place the cover 40 in position, it is placed in the depressed or countersunk portion 21 in the top wall 25 of the base member ll with the fingers 43 lined up with the aperture 29 in the top wall 25. When so positioned the ridges 44 will contact the wall 25 adjacent opposite sides of the aperture 29 and prevent the cover 40 from assuming a position, such as shown in Figs. 1 and 2.;However, the fingers 43 are resilient and aslight force applied to the top of the cover 40 will cause the fingers to be sprung toward each other by reason of the ridges 44 bearing against the top wall 25 of the base member ll adjacent the aperture 29, and the ridges 44 will snap through the aperture 29 and engage the under side of the top wall 25 of the base member ll adjacent the aperture 29, as shown in Fig. 5, and retain the cover 40 in position over the aperture 29.

The cover 49 may be easily snapped off by applying aslight force at 42 with ones finger nail or some flat tool such as a pen knife or screwdriver.

' From the foregoing description, taken in connection with the drawing, it is seen that this invention provides a fan including an improved arrangement for mounting it on a substantially vertical support or wall and an improved, economical, decorative cover for the mounting means that may be readily applied or removed from the 7 fan from the exterior thereof. This invention provides, also, a cover for the mounting means that may be attached to the fan without the use of fastening means visible from the exterior of the fan. i

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.

What I claim is:

1. In an electric fan or the like, a supporting pedestal having a flat bottom and a curved top wallsloping to a junction with said flat bottom, fastening means extending through an opening in said pedestal for engaging an external support, a cover for concealing said opening and said fastening means, spring clips carried by said cover and engaging said pedestal for removably retaining said cover in position, a portion of the lower edge of said cover being spaced from the corresponding portion of said fiat bottom to provide a normally invisible opening for the reception of means for disengaging said cover.

2. In an electric fan or the like, a pedestal in cluding a base having a flat bottom and a curved top wall, there being a depressed portion disposed near one end of 'saidtop wall and forming a'seat, fastening means extending through a hole in said depressed portion to engage an external support, a removable cover adapted to engage said seat for concealing said depressed portion, said hole and said fastening means, and spring clips depending from said cover and engaging the walls of an opening in said top wall for removably retaining said cover in position, there being an opening formed at the junction of said cover and said base affording access for means for disengagingsaid cover.
